The second correcting lens may be a convex lens or a concave lens. For example, the image transmitted through the concave lens in the image receiving unit 110 and reduced and reflected by the display unit 130 is totally reflected by the total reflection mirror. The mixed image in which the totally-captured image and the virtual reality image are overlapped can be enlarged through the convex lens. In addition, the image transmitted through the convex lens in the image receiving unit 110 and enlarged and reflected by the display unit 130 is totally reflected by the total reflection mirror. The mixed image in which the totally captured image and the virtual reality image overlap can be reduced by transmitting through the concave lens.

The chromatic aberration can be minimized by using a concave lens or a convex lens made of materials having different chromatic dispersion from each other for the first correcting lens and the second correcting lens.

When the first and second lenses are formed on both sides of the lens, the occurrence of partial reflection at the lens surface can be minimized and the transmittance can be increased.

According to an embodiment, the display portion 130 may include a transparent display pixel pattern 420.

According to an embodiment, P 430 reflects from the image 480 output directly from the transparent display pixel pattern 420 of the transparent display 132 and from the reflective surface 410 of the rear reflective mirror to form the glass layer 440 And the distance between the images 490 that are transmitted through the transparent display 132 and output.

To limit

The value should be reduced,

The reflective mirror must be a front reflective mirror rather than a rear reflective mirror, and the thickness of the transparent display 132 should be as thin as possible. By arranging the pixel pattern on the reflective surface 410 in the transparent display 132, the thickness of the transparent display 132 can be nearly zero.

5 is a cross-sectional view illustrating a front half of a head mounted display device according to an embodiment of the present invention.

Referring to FIG. 5, the display unit 130 of the head mounted display device includes a transparent display 132 and a total reflection unit 131. The transparent display 132 of the head mounted display device includes a transparent display pixel pattern 420, L (510), d (520).

According to the embodiment, the total reflection portion 131 of the head-mounted display device includes a total reflection mirror.

The total reflection part 131 according to the embodiment includes a reflection surface 530 located on the front surface of the total reflection mirror.

Since the total reflection mirror according to the embodiment does not have a glass layer, only the thickness of the transparent display 132 may cause the actual image to appear as two images.

[Equation 2]

는 사용자의 눈과 투명 디스플레이 픽셀 패턴(420)사이에 형성되는 시야각도로써, 최대값은 투명 디스플레이(132)의 FOV(Field of View)가 될 수 있다. L in Equation 2 represents the image 480 output from the transparent display pixel 420 of the transparent display 132 and the image 490 reflected from the reflective surface 530 of the total reflection mirror and transmitted through the transparent display 132 ), D 520 is the thickness of the transparent display 132,

Refers to the angle between the straight line and the image output to the user's eyes by drawing a straight line around the eye. Also,

Is the viewing angle formed between the user's eye and the transparent display pixel pattern 420 and the maximum value can be the field of view (FOV) of the transparent display 132.

In Equation (2), it is assumed that the distance from the user's eyes to the display 132 is much larger than the thickness d (520) of the display.

=45도, d=300

m 이라고 가정하면 최대 두 영상의 거리는 L=300

m 정도이므로 사용자는 눈에 직접 입사되는 영상(480)과 거울에 반사되어 입사되는 영상(490)의 가장 자리를 구분하기 어렵거나 불편하게 느끼지 않을 수 있다. 한편, d를 300

m으로 가정하는 이유는 현재 투명 디스플레이(132)에 포함되는 OLED의 두께가 300

m정도이기 때문이며, 디스플레이 관련 기술의 발전에 따라 d는 더 얇아질 수 있다.According to the embodiment, the phase can be separated by L (410) calculated in equation (2). E.g,

= 45 degrees, d = 300

m, the distance between the two images is L = 300

m, the user may not feel difficult or uncomfortable to recognize the edge of the image 480 directly incident on the eye and the image 490 reflected on the mirror. On the other hand, if d is 300

m because the thickness of the OLED included in the current transparent display 132 is 300

m, and d can be made thinner with the development of display related technology.

4, when a rear reflective mirror having a glass layer is used, a value obtained by adding the thickness of the transparent display and the thickness of the glass layer is substituted into d in Equation 1. The thickness of the rear reflective mirror is preferably 1 mm or more Value, the value of L of the above-described formula, which is calculated, can be visually recognized by a person. Therefore, the image outputted to the user's eyes can show two actual real images through refraction phenomenon and scattering phenomenon.

6, the difference between the two images becomes large. Therefore, as the transparent display pixel pattern 420 is disposed closer to the reflecting surface 530 of the total reflection mirror, as shown in FIG. 6, The distance between the direct input image 480 directly input to the mirror and the image 490 reflected by the mirror can be reduced.

FIG. 6 is a cross-sectional view illustrating a display pixel pattern located on a front surface of a display unit of a head-mounted display device according to an exemplary embodiment of the present invention.

6, the head mounted display device includes a total reflection part 131 and a transparent display 132, the transparent display 132 includes a transparent display pixel pattern 420, and the total reflection part 131 includes a total reflection part 132, And the total reflection mirror includes a reflecting surface 530 located on the front side.

According to one embodiment, a transparent display pixel pattern 420 may be disposed on the front side of the total reflection mirror.

For example, an actual real image 490 transmitted from the reflective mirror part is totally reflected at a reflection surface 530 located at the front of the total reflection mirror, and the transparent display pixel pattern 420 is reflected at the rear surface of the transparent display 132 , A virtual reality image 610 positioned directly on the front of the total reflection mirror and directly incident on the user wearing the head-mounted display device, and a real image 490 of total reflection on the reflection surface 530 of the total reflection mirror The difference in the image input to the eyes of the user wearing the head-mounted display device can be eliminated.
